Oh for god's sake, if it's really so bloody difficult, then we'll just split it up:

C:\> glomosim data.in > \path\to\some\dir\file.txt

C:\> mysuperawesomescriptthatdoessomething.pl \path\to\some\dir\file.t
+xt

Now I don't know what a "glomosim" is or what it does, so adjust the output redirection accordingly.
Good luck -- you'll need it if you show no interest in following the (very straightforward) advice already given to you.
